Skylab: The Human Side of a Scientific Mission
… focus then shifts to changes in NASA from the Apollo missions to Skylab, as well as training, before highlighting the three missions to the station. The work then attempts to show the significance of Skylab by focusing on the myriad of lessons that can be learned from it and applied to future …

Review of the mechanical properties of lunar soils
… lunar soil exploration through the Surveyor and Apollo programs, 1966 - 1972. Our current knowledge of the physical and engineering properties of the lunar regolith is derived mainly from measurements made on bulk and core samples returned to earth, as well as trenching, penetration and simple …

The Mothership: Multiplanetary Becomings and Reproducing Worlds
… NASA launched Artemis I, the first of multiple missions propelling humanity toward a multiplanetary future in which we will build new worlds, terraforming environments both physically and ideologically. These “moon to mars” missions mark a new era of deep space exploration, the first in fifty …

Human estimation of slope, distance, and height of terrain in simulated lunar conditions
… and on the Moon using photographs from the Apollo missions. Five experiments were conducted in field and Virtual Reality (VR) environments. The effects of true slope, true distance, and sun elevation on slope estimates were determined using visual and motor responses in a lunar-like Utah …

Simulating Apollo: Flight Simulation Technology 1945-1975
… heart and soul of the NASA system” during the Apollo program. At the intersection of automatic control systems, stability and control, and analog computing, aeronautical engineers developed simulators that functioned as “a fictious airplane in the electrical realm,” permitting real-time …

Simulation of rocket plume impingement and dust dispersal on the lunar surface
… because it allows for direct comparison to Apollo observations. Steady axisymmetric impingement was first studied for different thrust engines and different hovering altitudes. The erosion profiles are obtained from empirically derived scaling relationships and calibrated to closely match …

Robust Spacecraft Autonomy for Deep Space Exploration in Special Euclidean Group SE(3)
… that we have not truly left Earth since the Apollo, as spacecraft in some LEOs remain subject to atmospheric drag thus emphasizing their continued connection to Earth's immediate environment. Reflecting on this, it becomes clear that humanity has largely remained bound to Earth’s immediate …
